From 4d55129aea65ac23a34b9053f3f1ee4d92883032 Mon Sep 17 00:00:00 2001 From: Joe Fradley Date: Tue, 22 Nov 2022 14:54:49 -0800 Subject: UPSTREAM: crypto: x86/curve25519 - disable gcov curve25519-x86_64.c fails to build when CONFIG_GCOV_KERNEL is enabled. The error is "inline assembly requires more registers than available" thrown from the `fsqr()` function. Therefore, excluding this file from GCOV profiling until this issue is resolved. Thereby allowing CONFIG_GCOV_PROFILE_ALL to be enabled for x86.
